The Colombian government efforts to reduce the influence of drug-related criminal organizations is one of the origins of the Colombian conflict, an ongoing low-intensity war among rival narcoparamilitary groups, guerrillas and drug cartels fighting each other to increase their influence and against the Colombian government that struggles to stop them.

Worldwide demand of psychoactive drugs during the 1960 and 1970s eventually increased the production and processing of these in Colombia. Cocaine is produced at $1500/kilo in jungle labs and could be sold on the streets of the US for as much as $50,000/kilo.[2] The USA intervened in Colombia throughout this period in an attempt to cut off the supply of these drugs to the US. The drug barons of Colombia, such as Pablo Escobar and José Rodríguez Gacha were long considered by authorities to be among the most dangerous, wealthy and powerful men in the world.

According to Bloomberg News, as of 2011, studies show that Colombia is the world's largest cocaine producer.[3][4] The United States of America is the world's largest consumer of cocaine[5] and other illegal drugs.

Since the establishment of the War on Drugs, the United States and European countries have provided financial, logistical, tactical and military aid to the government of Colombia in order to implement plans to combat the illegal drug trade. The most notable of these programs has been the Plan Colombia which also intended to combat leftist organizations, such as the FARC guerrillas, who have controlled many coca-growing regions in Colombia over the past decades.

Despite Colombia having the dubious distinction of being the world leading producer of coca for many years[6] those plans, slowly but surely, diminished the drug produced, to the extent that, in 2010, the country reduced cocaine production by 60%, relative to the peak in 2000. In that same year, Peru surpassed Colombia as the main producer of coca leaves in the world.[4] The level of drug-related violence was halved in the last 10 years and dropped below that of countries like Honduras, El Salvador, Venezuela, Guatemala and Trinidad and Tobago.[citation needed]

Colombia has acted in a more aggressive way than most of the countries which signed the 1988 Vienna Convention Against Illicit Traffic in Narcotic Drugs and Psychotropic Substances, by including chemicals and drug precursors, that are freely traded in the rest of the world, in the list of nationally controlled substances.[7] Notwithstanding the internal production of drugs, the rate of internal consumption in Colombia is smaller than in the United States and in many of the countries of the European Union and absolute drug consumption is even smaller.[8]

Given the fact that the population of the United States is the largest user of illegal drugs in the world, with one in six citizens claiming to have used cocaine in their life,[9] the United Nations Office on Drugs and Crime (UNODC), after reviewing the efficiency of the actions taken by the Colombian government for more than 20 years, has called for cocaine consuming countries - mostly in Europe and North America - to take their share of responsibility and reduce demand for cocaine,[4] explaining that there are limits to what the Andean governments can do if cocaine consumption continues unabated, a position that has been maintained by the Colombian government for many years and was later accepted by the United States government.[10]

Colombia rejects threats and blackmail of the United States of America after the threat of Donald Trump to decertify the country as a partner in counter-narcotics efforts.[12]

For more than 30 years Colombia has demonstrated its commitment – paying a very high cost in human lives – with overcoming the drug problem. This commitment stems from the profound conviction that the consumption, production and trafficking of drugs constitute a serious threat to the well-being and security of citizens. Colombia is undoubtedly the country that has fought the most drugs and with more successes on this front. No one has to threaten us to meet this challenge.

The problem of drugs is global. Overcoming it can only be achieved through cooperation and under the principle of joint responsibility. Consumer countries’ authorities have a fundamental responsibility to their fellow citizens and the world to reduce consumption and to attack trafficking and distribution organizations in their own countries.

Many plantations provide prostitutes to sustain their employees. Sexually transmitted diseases are spread at a rapid pace and contribute to the workers' inability to heal from the flesh wounds and their incapability of survival outside of this environment.[17]

The few positive outcomes from the manufacturing of cocaine include temporarily providing a job for a family struggling financially and raising Colombia’s GDP and standard of living.[18]

Some psychoactive drugs were already grown in Colombia at limited level by local indigenous groups, who mostly employed marijuana and coca leaves for ceremonial and traditional medical uses as part of their culture.

With prohibition, established producers and traffickers formed armed and clandestine cartels. During the 1980s, as demand increased, the cartels expanded and organized into major criminal conglomerates usually headed by one or several kingpins as in the case of the Medellín Cartel and the North Coast Cartel, along with federation-style groups such as the Cali Cartel and Norte del Valle Cartel.

The Medellín Cartel led by Pablo Escobar established a ruthless organization, kidnapping or murdering those who interfered with its objectives. The Medellín Cartel was responsible for the murders of hundreds of people, including government officials, politicians, law enforcement members, journalists, relatives of same, and innocent bystanders. The cartel sometimes cooperated with guerrilla groups such as the M-19, to process and protect illegal drugs. When conflicts emerged between the Medellín Cartel and the guerrillas, the cartel also promoted the creation of paramilitary groups.

The cartel originally imported most coca from Bolivia and Peru, processing it into cocaine inside Colombia and then distributing it through most of the trafficking routes and distribution points in the U.S., including Florida, California and New York.

The pressure mounted by the US and Colombian governments to counter them led to the cartel's destruction. Most of the cartel's associates were gunned down by police and military forces or turned themselves in to authorities in exchange for lenient prison terms.[20]

The Cali Cartel, also known as "Cali's Gentlemen", was based in southern Colombia, around the city of Cali and the Valle del Cauca Department. The Cali Cartel was founded by the Rodríguez Orejuela brothers, Gilberto and Miguel, as well as associate José Santacruz Londoño. The Cali Cartel originally began as a ring of kidnappers known as Las Chemas. The profits of kidnapping helped finance the ring's move to drug trafficking, originally beginning in Marijuana and eventually spreading to cocaine. The cartel's estimated revenue would eventually reach an estimated $7 billion a year.[21][22][23]

The cartel's influence spread to the political and justice system. It also played a role in the manhunt that led to the death of Pablo Escobar and helped form the vigilante group "Los Pepes", which worked alongside members of the government's elite Bloque de Busqueda, exchanging information on the whereabouts of Escobar and key figures in the Medellín Cartel.

After the collapse of the cartel, it was discovered it was wiretapping phone calls made into and out of Bogotá,[24][25] and was engaged in money laundering using numerous front companies spread throughout Colombia.

The Norte del Valle cartel is estimated to have exported more than 1.2 million pounds – or 500 metric tons – of cocaine worth in excess of $10 billion from Colombia to Mexico and ultimately to the United States for resale in past year. Indictments filed in the United States charge the Norte del Valle cartel with using violence and brutality to further its goals, including the murder of rivals, individuals who failed to pay for cocaine, and associates who were believed to be working as informants.

Leaders of the Norte del Valle cartel were further alleged to have bribed and corrupted Colombian law enforcement and Colombian legislators to, among other things, attempt to block the extradition of Colombian narcotics traffickers to the United States for further prosecution. According to the indictments filed in the United States, members of the Norte del Valle cartel even conducted their own wiretaps in Colombia to intercept the communications of rival drug traffickers and Colombian and United States law enforcement officials.

The cartel is believed to have employed the services of the United Self-Defense Forces of Colombia (AUC), a right-wing paramilitary organization internationally classified as a terrorist organization, to protect the cartel’s drug routes, its drug laboratories, and its members and associates. The AUC is one of the 37 Foreign Terrorist Organizations identified by the U.S. State Department in 2004.

The North Coast Cartel was based in the Colombian city of Barranquilla by the Caribbean coast and was headed by Alberto Orlandez-Gamboa "Caracol" (the snail), who was considered as ruthless as Pablo Escobar. The organization transshipped significant amounts of cocaine to the United States and Europe via the smuggling routes it controlled from Colombia's North Coast through the Caribbean. As head of the organization, Gamboa depended on his close associates to conduct the organization's operations and to insulate himself.[27]

As is typical with many Colombia-based organizations, Gamboa compartmentalized his business dealings. In addition, the success of Caracol's Barranquilla-based drug trafficking organization was attributed, in part, to the respect the drug organization received from other traffickers operating on Colombia's North Coast. DEA Intelligence indicated that traffickers paid taxes to Gamboa's organization in order to be allowed to ship drugs out of the North Coast. His influence in this region was so strong that traffickers even asked him for permission before conducting assassinations.[27]

On June 6, 1998, Caracol was arrested in Barranquilla, as a result of an ongoing joint investigation between DEA's Barranquilla Resident Office and the Colombian National Police. After his arrest, Caracol immediately was flown to Bogotá, where he was held on murder, kidnapping, and terrorism charges. He was extradited to the United States in August 2000. On March 13, 2003, Caracol pleaded guilty to participating in a narcotics trafficking conspiracy that smuggled tens of thousands of kilograms of cocaine into New York and other cities. His plea was announced on the morning he was to go on trial in Federal District Court in Manhattan after losing a crucial appellate ruling.[27] With the capture of Gamboa the North Coast Cartel structure was later dismantled by the Colombian National Police.[28]

New paramilitary groups and related drug trafficking organizations that have continued operating after the AUC demobilization process are referred to as bandas criminales emergentes[29][30] or BACRIM (Spanish for "emerging criminal organizations") by the Colombian government.[31]

Until 2011, Colombia remained the world's largest cocaine producer.[3] Since 2003, Human Rights Watch stated that, according to their Colombian intelligence sources, "40 percent of the country's total cocaine exports" were controlled by these paramilitaries.[32][33][34][35][36] And in 2011 an independent investigation made by the Colombian newspaper El Tiempo estimated that 50% of all Colombian cocaine was controlled by the same BACRIM groups.[37][38]

According to the Colombian National Police, these groups had 3,749 members by July 2010.[39] The NGOInstituto de Estudios para el Desarrollo y la Paz has indicated they would have approximately 6,000 armed combatants.[39] Others estimate their ranks may include up to 10,000 people.[31][40]

The successor groups are often made up of mid-level paramilitary commanders and criminal structures that either did not demobilize in the first place or were re-activated after the demobilizations had concluded.[39][40] Many demobilized paramilitaries received recruitment offers, were threatened into joining the new organizations or have simultaneously rearmed and remained in government reintegration programs. New recruits have also come from traditional areas for paramilitary recruitment.[40]

The main emerging criminal and paramilitary organizations are known as:

These groups continue to be involved in the drug trade, commit widespread human rights abuses, engage in forced displacement and undermine democratic legitimacy in other ways, both in collusion with and opposition to FARC-EP guerrillas.[31][39][49] Their targets have included human rights defenders, labor unionists and victims of the former AUC. Members of government security forces have also been accused of tolerating their growth.[39][49]

In December 2010, ERPAC paramilitary leader Pedro Guerrero, also known as Cuchillo or "Knife", died after a police raid.[50][51]

Perhaps the greatest threat posed to the Medellín Cartel and the other traffickers was the implementation of an extradition treaty between the United States and Colombia. It allowed Colombia to extradite any Colombian suspected of drug trafficking to the US and to be put on trial there for their crimes.

This was a major problem for the cartel since the drug traffickers had little access to their local power and influence in the US, and a trial there would most likely lead to imprisonment. Among the staunch supporters of the extradition treaty were Colombian Justice Minister Rodrigo Lara Bonilla, Police Officer Jaime Ramírez and numerous Supreme Court Judges.

However, the cartel applied a "bend or break" strategy towards several of these supporters. When attacks against the police began to cause major losses, some of the major drug lords themselves were temporarily pushed out of Colombia, going into hiding while they ordered cartel members to take out key supporters of the extradition treaty.

During the 1980s, the Medellín Cartel leader Pablo Escobar, who already possessed considerable wealth, attempted expand his influence and notoriety by entering into Colombian political life through the political movement of liberal leaderLuis Carlos Galán named New Liberalism. Escobar succeeded in becoming deputy to congressman Alberto Santofimio, but after the provenance of Escobar's wealth and his mounting influence were made a public controversy Galán was forced to reject him from his political movement and pushed for an extradition treaty with the United States.

Another member of the Medellín Cartel, Carlos Lehder, used his cocaine wealth to make a push for political power. His movement was populist, funding free education and health programs in rural areas and the construction of homes for slum-dwellers. His rhetoric was also anti-American, anti-Russian and anti-imperialist. His program showed similarities with that of Pablo Escobar, who paid for lighting to be installed in local football clubs and also paid for housing for slum-dwellers. The active political stance of some members of the Medellín Cartel was a significant factor in the attempts of the Colombian state to destroy their influence in the country.[52]

In contrast, the Cali Cartel adopted a much more subtle and non-confrontational attitude. Many of its bosses were from already wealthy and influential families, and they tended to invest their earnings from the cocaine trade in legitimate businesses. This often included complementary businesses, such as pharmacy and chemical manufacturing, which provided a cover for the purchase of the chemicals needed to refine the coca-paste purchased in the coca-growing regions into cocaine for export to the USA.

The cartel's non-confrontational strategy and its integration within the existing power structure, in contrast to the political challenge attempted by members of the Medellín Cartel, meant that they were threatened much less by law enforcement, from both Colombian investigators and the DEA. The head of the DEA in Bogotá said that in comparison with the Medellín bosses, the Cali bosses were "more refined, more cultured". The DEA regularly left the Cali Cartel alone in exchange for information that would allow them to arrest figures from the Medellín Cartel.

During the 1980s the Medellín Cartel led by Pablo Escobar was at its height and the U.S. and Colombian governments were moving towards enforcing laws regarding the illegal drug trade. The Medellín Cartel associated with 19th of April Movement (M-19) guerrilla among others to rely on them the production and processing of the illegal drugs. The guerrillas saw in the illegal drug trade a form of financing their guerrilla movement. Other guerrillas such as FARC and ELN followed the same example and also began collecting taxes on small illegal drug trafficking organizations to improve their financial stability.[53]

With the fall of the two main drug trafficking cartels of Medellín and Cali in the 1990s, some of organizations that inherited their drug routes were members of the newly formed Norte del Valle Cartel. The FARC and ELN guerrillas came to control the coca-growing regions in the Colombian Amazon and to tax the income from the sale of coca-paste. The right-wing para-military groups initially grew out of the private armies of cocaine cartels.[54]

Para-military groups such as the AUC assassinated trade unionists, left-wing priests and any others deemed to be leftist sympathists. They have also collaborated with Colombian state forces. "The strengthening of the Revolutionary Armed Forces of Colombia (FARC) during the 1990s was an unintended consequence of a series of tactical successes in U.S. anti-drug policies. These included dismantling the Medellín and Cali drug cartels, interdicting coca coming into Colombian processing facilities, and using drug certification requirements to pressure the Colombian government to attack drug cartels and allow aerial fumigation of coca crops. These successes, however, merely pushed coca cultivation increasingly to FARC-dominated areas while weakening many of the FARC's political-military opponents. This provided the FARC with unprecedented opportunities to extract resources from the cocaine industry to deepen its long insurgency against the Colombian state."[54]
